METHODS AND APPARATUSES FOR SPECTRUM DISTRIBUTION IN D2D COMMUNICATION

Abstract:

Embodiments of the present disclosure provide methods and apparatuses for spectrum distribution in D2D communication. A method implemented at a policy management network element in a communication system comprises: in response to receiving (210) an attach request or a location update request from a terminal device transmitted by a policy execution network element in the communication system, generating, at the policy management network element, a policy for the spectrum distribution in the D2D communication for the terminal device; and transmitting (220) the generated policy to the policy execution network element for use in the spectrum distribution in the D2D communication for the terminal device. Thus, a dynamic and flexible spectrum distribution mechanism based on policy control can be provided for D2D communication, thereby taking full advantage of limited spectrum resource in D2D communications for the maximum benefit.
